Definitions

  • Plastic pollution is one of the most pressing environmental issues that must be addressed. Plastic does not decompose, and therefore all plastic that has ever been produced is still present in one form or another. While recycling has made a small impact on the reduction of plastics in landfills and oceans, there remains far too much plastic in the products used by consumers in everyday life. Furthermore, plastic is made from materials that include coal, salt, crude oil, and toxic materials such as benzene and vinyl hydrochloride. Many goods manufacturers are therefore working to reduce their plastic output to reduce the amount of plastic sitting in landfills and oceans. The invention described herein seeks to address these issues by reducing the amount of plastic in personal care implements such as toothbrushes without negatively affecting consumer enjoyment during use of the same.
  • the present invention is directed to a personal care implement that uses less plastic by removing material from a handle of the oral care implement while maintaining a comfortable grip which is similar to a normal grip that a user associates with a personal care implement. That is, the handle has a recess in a rear surface thereof, such that the handle or a portion thereof has a U-shaped transverse cross-sectional area. Portions of the handle may be covered with an elastomeric material to increase gripability and comfort.
  • the handle may also include various rib structures elongated along the recess to increase the strength of the handle so that it does not significantly deform during normal use.
  • the invention may be a personal care implement comprising: a body extending along a longitudinal axis and comprising a head configured to perform a personal care function and a handle configured to be gripped by a user during performance of the personal care function, the handle comprising a thumb grip portion and a finger grip portion that extends from the thumb grip portion to a distal end of the handle that is located furthest from the head; and wherein the finger grip portion of the handle has a generally U-shaped transverse cross-sectional area along an entirety of a length of the finger grip portion from the distal end of the handle to the thumb grip portion of the handle.
  • the invention may be a personal care implement having a longitudinal axis and comprising: a head configured to perform a personal care function; a handle coupled to the head and configured to be gripped by a user during performance of the personal care function, the handle comprising a distal axial portion that comprises a distal end of the handle that is located furthest from the head; and wherein the distal axial portion of the handle comprises: a recess that is elongated in a direction of the longitudinal axis; a first portion formed from a rigid material and comprising a front surface that is convex in a direction transverse to the longitudinal axis, a rear surface opposite the front surface that forms a floor of the recess and is concave in the direction transverse to the longitudinal axis, and a distal edge extending between the front and rear surfaces that at least partially surrounds the recess; and a second portion formed from an elastomeric material that covers the distal edge of the first portion.
  • the invention may be a personal care implement having a longitudinal axis and comprising: a head configured to perform a personal care function; a handle coupled to the head and configured to be gripped by a user during performance of the personal care function, the handle comprising a distal axial portion that comprises a distal end of the handle that is located furthest from the head; wherein the distal axial portion of the handle comprises: an arcuate shaped rigid portion having a convex front surface, a concave rear surface, and a distal edge extending between the convex front surface and the concave rear surface; and an elastomeric portion covering and extending from the distal edge of the arcuate shaped rigid portion.

Abstract

La présente invention concerne un dispositif de soins personnels qui utilise moins de plastique en éliminant un matériau d'un manche du dispositif de soin buccal tout en maintenant une prise confortable qui est similaire à une prise normale qu'un utilisateur associe à un dispositif de soins personnels. À savoir, le manche comporte un évidement dans la surface arrière de celui-ci, de sorte que le manche ou une partie de celui-ci présente une section transversale transversale en forme de U. Des parties du manche peuvent être recouvertes d'un matériau élastomère pour augmenter l'adhérence et le confort. Le manche peut comprendre en outre différentes structures de nervure allongées le long de l'évidement pour augmenter la résistance du manche de sorte qu'il ne se déforme pas significativement pendant une utilisation normale.
